090 call parens hug args

✓ Passing Passing: the compiler rejects this program as expected.

Code

// Pins: a call whose '(' does not hug its first argument is a parse
// refusal — 'adx( 7, ...' is C-style spacing, not Koru. The ')' edge is
// refused by the same rule.
import std/io

adx -> qlen + dx

use = adx( 7, dx: 3): m
